SPRING-GILER.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed April 30, 1920. Serial No. 377,955.

To @Zizo/10m t may concern Be it known that we, Anim E. JorrNsoN and Lno H. Tarifen-n, citizens of the United States, residing at Hastings, county of Barry, State of Michigan, have invented certain new and useful Improvements in Spring-Oilers, of which the following is a specification.

This invention relates to improvements in spring oilers.

The main objects of this invention are:

First, to provide an improved spring oiler which is adapted to springs of different sizes or cross dimensions.

Second, to provide an improved spring oiler having these advantages, the body or casing part of which is formed in the fiat so that a set of the oilers may be arranged in a very compact package and may be quickly adjusted or applied to the springs of a motor vehicle or the like.

Further objects, and objects relating to structural details, will deiinitely appear from the detailed description to follow.

We accomplish the objects of our invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of our invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a side view of an oiler embodying the features of our invention applied to a leaf spring, the spring being partially broken away.

Fig. II is a detail longitudinal section on a line corresponding to line 2--2 of Fig. III.

Fig. III is a transverse section on a line correspondingr to line 33 of Figs. I and II.

Fig. IV is a plan view of the casing member of our improved oiler in the flat or eX- tended position and beforethe pad is attached thereto.

Fig. V is an inside view of our improved oiler in the flat with the pad in position.

Fig. VI is an enlarged detail section on a line corresponding to line 6-6 of Fig. V.

Fig. VH is a plan view ofthe lubricant chamber bottom.

In the drawing similar reference characters refer to similar' parts throughout the several views, and the sectional views are taken looking in the direction of' the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents a spring of the leaf type.

@ur improved oiler comprises a body or casing member 2 of bendable sheet metal having serrated longitudinal edges providing teeth 3 and a struck-up portion 4L at the center providing a lubricant chamber 5.

The casing member may be satisfactorily formed of quite light sheet metal as there is little strain thereon in use.

We provide a bottom 6 for the lubricant chamber (see Fig. VH), the bottom having 11p-turned marginal flanges 7 which iit within the struck-up portion of the casing member. An opening S is provided in the top of the struck-up portion for the introduction of the lubricant. a pivoted closure 9 being provided for this opening.

The bottom 6 is provided with holes l0 for the discharge of thc lubricant to the pad l1. This pad is preferably a piece of felt and is arranged on the under side of the casing member and secured thereto by folding the teeth or lugs 12 on to the edges of the pad.

The casing member has a series of longitudinally spaced holes 13 therein adapted to receive the attaching bolt 14 which is passed through the holes below the spring to which the oiler is applied. The pad has longitudinal slots 15 registering with the holes.

Our improved oilers are shipped in the flat as shown in Fig. V and in applying them, they are placed upon the spring to which they are to be attached with the oil chamber centrally thereof and the ends bent downwardly or wrapped about the sides of the spring as shown and secured by means of the attaching bolt.

The oilers may thus be fitted to springs of different sizes and at the particular point at which it is desired to apply them.

Our improved oilers are very economical to produce and, as stated, may be applied to springs of varying sizes thus-avoiding the necessity of having a variety of sizes of Oilers. They are also very eiiicent, as the lubricant passes from the chamber into the pad by Which it is carried by capillarity to the edges of the springs.

Having thus described our invention, What We claim as new and desired to secure by Letters Patent, is:

l. In a spring oiler, the combination of a casing member` of bendable sheet metal adapted to be bent over and conformed to the top and sides of a spring and having serrated longitudinal edges providing pad holding teeth, a central portion of said casing member being struck up to provide a lubricant chamber, a bottom. forsaid lubricant chamber having 11p-turned edge flanges fitting Within the chamber, said bottom having an oil delivery opening therein, the ends of said casing member being provided With a. plurality: of holes spaced longitudinally thereof and to receive an attaching bolt, a pad of felt arranged on the inside of said casing member across said lubricant chamber, the teeth of. said casing member being engaged on the edges of the pad, said pad having slots at its ends registering with said bolt holes, and an attaching bolt. y

2. In a spring oiler, the combination of a easing member ofbendable sheet metal adapted to be bent over and conformed to the top and sides of a spring and having serrated longitudinal edges providing pad holding teeth, a central portion of said casing member being struck up to provide a lubricant'chamber, a bottom for said lubricant chamber having 11p-turned edge flanges itting Within the chamber, said bottom having an oil delivery opening therein, apad of felt arranged on the inside of said casing meml ber, the teeth of said easing member being en- 'gaged on the edges of the pad, and an attaching bolt arranged through the ends of said casing member below the spring on which it is mounted.

3. In a spring oiler, the combination of a casing member of bendable sheet metal adapted to be bent over and conformed to the top and sides of a spring and having serrated longitudinal edgcs providing pad holding teeth, 'a central portion of said casing member being struck up to provide a lubricant chamber, the ends of said casing member being provided with a plurality of holes spaced longitudinallyT thereof and to receive an attaching bolt, a pad of felt arranged on the inside of said casing member, the teeth of said casing member being engaged on the edges of the pad, said pad having slots at its ends registering with said bolt holes, and an attaching bolt. v Y

4. In a spring oiler, the combination of a casing member of bendable sheet metal adapted to be bent over and conformed to the top and sides of a spring and having pad holding teeth on its longitudinal edges, aV

central portion of said casing member being struck up to provide a lubricant chamber, the ends of said casing member being provided vvith a plurality of holes spaced longitudinally thereof and to receive an attaching bolt, a pad of felt arranged on the inside of said casing member and engaged by its said pad holding teeth, and an attaching bolt.

In Witness whereof we have hereunto set our hands and seals in thc presence of two Witnesses.
